Description

Technical Field

[0001] This application relates to environmental protection equipment, and in particular to a post-treatment device for associated gases from high-temperature carbonization of biomass. Background Technology

[0002] Against the backdrop of a global energy structure shift towards low-carbon and renewable energy sources, the resource utilization of agricultural and forestry waste such as straw and sawdust has become a crucial approach to addressing energy shortages and environmental issues. High-temperature carbonization technology, as a core method of biomass resource utilization, can convert straw and sawdust into high-value-added products such as biochar and combustible gases, which are widely used in soil improvement, energy supply, and industrial adsorption. According to relevant industry data, my country can efficiently convert tens of millions of tons of waste annually through biomass carbonization technology, demonstrating significant economic and ecological benefits. However, the high-temperature carbonization process (typically between 400-800℃) generates a large amount of complex waste gas and liquid. The waste gas mainly contains combustible gases such as methane and carbon monoxide, mixed with harmful impurities such as tar, dust, and hydrogen sulfide. Direct emission would not only cause air pollution but also pose safety hazards of combustion and explosion. The waste liquid contains pollutants such as phenolic compounds, organic acids, and suspended particulate matter, with COD (chemical oxygen demand) values ​​generally reaching 5000-20000 mg / L, far exceeding national industrial wastewater discharge standards. Direct discharge into natural water bodies or soil without treatment would severely damage the ecological environment, leading to soil acidification, eutrophication, and other problems, thus hindering the large-scale promotion and application of biomass carbonization technology. Therefore, developing efficient, continuous, and stable post-treatment devices for biomass carbonization waste gas and waste liquid has become a key technological bottleneck for promoting the healthy development of the biomass resource utilization industry.

[0003] Currently, domestic and international research and technological development have been carried out on the treatment of waste gas and waste liquid from biomass carbonization. However, existing technologies still have many shortcomings and are difficult to meet the continuous and efficient treatment needs of actual production. Application number CN202020906338.4, entitled "A Biomass Pyrolysis Gas Purification Device," discloses a biomass pyrolysis gas purification device based on a water washing tower. This device uses a spray structure within the water washing tower to cool the pyrolysis gas and remove impurities, utilizing the contact between water and gas to capture impurities such as tar and dust. However, this technology is only designed for gaseous media and does not consider the treatment needs of waste liquid generated simultaneously during carbonization. It requires an additional independent waste liquid treatment device, resulting in low system integration, a large footprint, and the water washing tower adopts a single-tower intermittent operation mode. When the liquid accumulation in the tower reaches a certain level, it needs to be shut down for cleaning, making 24-hour continuous operation impossible. The treatment efficiency is difficult to match the capacity requirements of large-scale carbonization production lines. Application number CN202411745670, entitled "A Continuous Pyrolysis and Carbonization System and Method for Biomass," proposes a continuous processing system comprising a pyrolysis unit, a bio-oil collection unit, and a CO2 removal unit. While it achieves waste gas purification through gradient condensation to recover bio-oil and remove CO2, thus realizing the continuity of the pyrolysis process, the system only designs the processing flow for gaseous products and does not consider the treatment needs of the high-concentration waste liquid generated during carbonization. This necessitates additional waste liquid treatment equipment, resulting in low system integration and increased investment costs. Furthermore, its bio-oil collection unit relies on a serpentine condenser for condensation and separation, lacking the ability to remove suspended particulate matter from the waste liquid and failing to achieve simultaneous purification of gaseous and liquid impurities. Application number CN202420524353.0, entitled "A High-Concentration Organic Waste Liquid Mixed Biomass Pyrolysis Gasification System", discloses a system that mixes biomass pyrolysis products with organic waste liquid for gasification. The system achieves organic matter decomposition through high-temperature treatment in a gasifier. Although it can co-process waste liquid and pyrolysis products, the core objective of this system is to produce syngas. It does not have a dedicated purification design for the waste gas generated simultaneously during the carbonization process. Impurities such as tar and hydrogen sulfide in the waste gas can directly enter the gasification system, which can easily cause equipment corrosion and blockage. Furthermore, the system does not have an independent waste liquid sedimentation and separation unit, making it difficult to meet the purity standards of the treated waste liquid and thus failing to meet environmental emission requirements.

[0004] Existing technologies for treating waste gas and waste liquid from biomass carbonization generally suffer from problems such as "gas-liquid separation, intermittent operation, and insufficient adaptability to operating conditions," failing to meet the demands for continuous, efficient, and synergistic treatment of waste gas and waste liquid in large-scale biomass carbonization production. Therefore, developing a post-treatment device that integrates simultaneous gas-liquid treatment, enables continuous operation, and is adaptable to the complex composition of biomass carbonization waste gas and waste liquid is of significant practical importance and application value for promoting the green and sustainable development of the biomass resource utilization industry. Summary of the Invention

[0005] The purpose of this invention is to provide a post-processing device for associated gas from high-temperature biomass carbonization, which enables simultaneous gas-liquid purification and continuous post-processing, meeting the environmental protection and efficiency requirements of large-scale carbonization production.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] This application discloses a post-processing device for associated gas from high-temperature biomass carbonization, including a frame and a gas-liquid inlet unit, a gas-liquid spray purification unit, and a gas-liquid outlet unit installed on the frame.

[0008] The gas-liquid inlet unit includes an air inlet flange pipe and a liquid inlet flange pipe. After the air inlet flange pipe is split, it is connected to a high-temperature resistant air inlet solenoid valve one and a high-temperature resistant air inlet solenoid valve two respectively. After the liquid inlet flange pipe is split, it is connected to a high-temperature resistant liquid inlet solenoid valve one and a high-temperature resistant liquid inlet solenoid valve two respectively. The air inlet flange pipe is used to introduce waste gas, and the liquid inlet flange pipe is used to introduce waste liquid.

[0009] The gas-liquid spray purification unit includes two groups. The first group includes spray purification tank 1, spray purification tank 3, spray purification tank 5 and static purification tank 1 connected in sequence through tank connecting pipes. The second group includes spray purification tank 2, spray purification tank 4, spray purification tank 6 and static purification tank 2 connected in sequence through tank connecting pipes. It also includes atomizing spray heads respectively installed at the top of spray purification tank 1, spray purification tank 2, spray purification tank 3, spray purification tank 4, spray purification tank 5 and spray purification tank 6. The atomizing spray heads spray the gas and liquid to cool and purify it.

[0010] The gas-liquid discharge unit includes an exhaust pipe 1, an exhaust pipe 2, a liquid discharge pipe 1, and a liquid discharge pipe 2. An exhaust valve 1, an exhaust valve 2, a liquid discharge valve 1, and a liquid discharge valve 2 are respectively installed on the exhaust pipe 1 and the exhaust pipe 2. An electromagnetic igniter 1 and an electromagnetic igniter 2 are respectively installed at the tail ends of the exhaust pipe 1 and the exhaust pipe 2.

[0011] The first high-temperature resistant air intake solenoid valve and the first high-temperature resistant liquid intake solenoid valve are respectively connected to the upper and lower sides of the first spray purification tank. The second high-temperature resistant air intake solenoid valve and the second high-temperature resistant liquid intake solenoid valve are respectively connected to the upper and lower sides of the second spray purification tank. The first exhaust pipe and the first drain pipe are respectively connected to the upper and lower sides of the second static purification tank. The second exhaust pipe and the second drain pipe are respectively connected to the upper and lower sides of the first static purification tank.

[0012] Preferably, in the above-mentioned post-treatment device for associated gas from high-temperature carbonization of biomass, the first high-temperature resistant air inlet solenoid valve and the second high-temperature resistant air inlet solenoid valve are used to control the introduction of waste gas, and the first high-temperature resistant liquid inlet solenoid valve and the second high-temperature resistant liquid inlet solenoid valve are used to control the introduction of waste liquid.

[0013] Preferably, in the above-mentioned post-processing device for associated gas from high-temperature biomass carbonization, the atomizing spray head is connected to the spray conveying pipe, the spray conveying pipe is connected to the spray hydraulic pump, and the spray hydraulic pump is used to convey liquid to the atomizing spray head.

[0014] Preferably, in the above-mentioned post-processing device for biomass high-temperature carbonization associated gas, the spray hydraulic pump includes spray hydraulic pump one, spray hydraulic pump two, spray hydraulic pump three, and spray hydraulic pump four. Spray hydraulic pump one acts on the atomizing spray head in spray purification tank two and spray purification tank four through a spray delivery pipe. Spray hydraulic pump two acts on the atomizing spray head in spray purification tank six through a spray delivery pipe. Spray hydraulic pump three acts on the atomizing spray head in spray purification tank one and spray purification tank three through a spray delivery pipe. Spray hydraulic pump four acts on the atomizing spray head in spray purification tank five through a spray delivery pipe.

[0015] Preferably, the post-processing device for associated gas from high-temperature carbonization of biomass also includes observation windows respectively disposed on the top of the spray purification tank 1, spray purification tank 2, spray purification tank 3, spray purification tank 4, spray purification tank 5, spray purification tank 6, static purification tank 1, and static purification tank 2, for observing the internal condition of the tank.

[0016] Preferably, in the above-mentioned post-processing device for associated gas from high-temperature carbonization of biomass, the electromagnetic igniter one and the electromagnetic igniter two are used to process the combustible gas.

[0017] Preferably, in the above-mentioned post-processing device for associated gas from high-temperature carbonization of biomass, the first high-temperature resistant solenoid valve and the second high-temperature resistant solenoid valve independently control the gas inlet path, and the first high-temperature resistant liquid inlet valve and the second high-temperature resistant liquid inlet valve independently control the liquid inlet path; by selectively opening and closing the solenoid valves, the two sets of gas-liquid spray purification units work alternately, thereby realizing the continuous operation of the post-processing process.

[0018] Compared with existing technologies, the advantages of this technical solution are as follows: By utilizing two independently controlled high-temperature resistant air inlet solenoid valves and high-temperature resistant liquid inlet solenoid valves in the gas-liquid inlet unit, precise switching of the gas-liquid inlet path can be achieved. This allows the two sets of tanks in the gas-liquid spray purification unit, consisting of a spray purification tank and a settling purification tank, to alternately operate in "working purification state" and "settling sedimentation state." When the first set of tanks is performing gas-liquid spray cooling and purification, the second set of tanks can simultaneously complete impurity settling and separation. When the first set of tanks needs cleaning, the system switches to the second set of tanks. This allows for continuous connection between impurity treatment and gas-liquid purification without stopping the machine, completely solving the problems of processing interruption and low efficiency caused by "intermittent operation" in existing technologies, and ensuring that the device can meet the requirements of 24-hour continuous operation.

[0019] The gas-liquid spray purification unit of this invention, through the synergistic action of the spray hydraulic pump, spray delivery pipe, and atomizing spray head, can atomize the spray liquid and ensure full contact with the gas-liquid mixture. This not only achieves efficient cooling but also comprehensively captures tar, dust, hydrogen sulfide in the waste gas and suspended particulate matter in the waste liquid. Simultaneously, the settling purification tank can further settle and precipitate the sprayed liquid phase, enhancing the separation effect of soluble impurities and fine particulate matter. Compared with existing technologies that can only target single-phase pollutants or lack deep sedimentation and separation processes, this invention removes various pollutants from carbonization waste gas and waste liquid more thoroughly, and the treated gas-liquid emission indicators are more likely to meet national industrial environmental protection standards.

The atomizing spray heads 216 spray the gas and liquid to cool and purify them.

[0031] The gas-liquid discharge unit 300 includes an exhaust pipe 304, an exhaust pipe 309, a drain pipe 305, and a drain pipe 310. Exhaust valves 303, 308, 302, and 307 are respectively installed on the exhaust pipes 304, 309, 305, and 310. Electromagnetic igniters 301 and 302 are respectively installed at the tail ends of the exhaust pipes 304 and 309.

[0032] High-temperature resistant air intake solenoid valve 102 and high-temperature resistant liquid intake solenoid valve 105 are respectively connected to the upper and lower sides of the spray purification tank 201. High-temperature resistant air intake solenoid valve 203 and high-temperature resistant liquid intake solenoid valve 206 are respectively connected to the upper and lower sides of the spray purification tank 202.

Exhaust pipe 209 and drain pipe 210 are respectively connected to the upper and lower sides of the static purification tank 207.

[0033] High-temperature resistant air intake solenoid valve 102 and high-temperature resistant air intake solenoid valve 103 are used to control the introduction of exhaust gas, and high-temperature resistant liquid intake solenoid valve 105 and high-temperature resistant liquid intake solenoid valve 106 are used to control the introduction of waste liquid. Atomizing spray head 216 is connected to spray delivery pipe 212, which is connected to spray hydraulic pump. The spray hydraulic pump is used to deliver liquid to atomizing spray head 216. The spray hydraulic pumps include spray hydraulic pump one 209, spray hydraulic pump two 210, spray hydraulic pump three 213, and spray hydraulic pump four 214. Spray hydraulic pump one 209 acts on the atomizing spray head 216 in spray purification tank two 202 and spray purification tank four 204 through spray delivery pipe 212. Spray hydraulic pump two 210 acts on the atomizing spray head 216 in spray purification tank six 206 through spray delivery pipe 212.

[0035] Electromagnetic igniter 1 301 and electromagnetic igniter 2 302 are used to treat combustible gases. High-temperature resistant gas inlet solenoid valve 1 102 and high-temperature resistant gas inlet solenoid valve 2 103 independently control the gas inlet path, and high-temperature resistant liquid inlet solenoid valve 1 105 and high-temperature resistant liquid inlet solenoid valve 2 106 independently control the liquid inlet path. By selectively opening and closing the solenoid valves, the two sets of gas-liquid spray purification units 200 work alternately, thereby realizing the continuous operation of the post-treatment process.

[0036] In practice,

[0037] Connect the gas-liquid inlet unit, gas-liquid spray purification unit, and gas-liquid outlet unit with appropriate piping and fix them to the frame, ensuring that all components are securely connected, well-sealed, and leak-free. Check the electrical connections and functions of all high-temperature resistant solenoid valves, spray hydraulic pumps, electromagnetic igniters, and other equipment to ensure they are normal, and that the observation windows are clean and provide a clear view.

[0038] Start spray hydraulic pumps one and three to deliver the spray liquid through the spray delivery pipe to the atomizing spray heads in the first set of tanks. The atomized spray liquid comes into full contact with the incoming gas-liquid mixture, achieving cooling of the mixture while efficiently capturing impurities such as tar, dust, hydrogen sulfide, and suspended particulate matter in the waste liquid. The gas and liquid flow sequentially through the tank connecting pipes in the first set of tanks, finally entering the first settling and purification tank for settling and sedimentation, further separating soluble impurities and fine particulate matter. Operators monitor the processing status of the gas and liquid and the sedimentation of impurities in the first set of tanks in real time through the observation window.

[0039] After the first set of tanks has been running for a period of time, the high-temperature inlet solenoid valve 1 and the high-temperature inlet liquid solenoid valve 1 are closed, while the high-temperature inlet solenoid valve 2 and the high-temperature inlet liquid solenoid valve 2 are opened simultaneously, allowing the gas and liquid to enter the second set of tanks, which consists of spray purification tank 2, spray purification tank 4, spray purification tank 6, and settling purification tank 2. At this time, spray hydraulic pump 2 and spray hydraulic pump 4 are started, repeating the above process of spraying, flow, and settling sedimentation, realizing the "working purification" of the second set of tanks. Meanwhile, the first set of tanks enters the "settling sedimentation" state, utilizing the settling time to complete the full separation of impurities without the need for shutdown for cleaning, thus ensuring continuous operation of the equipment.

[0040] For the gas treated by the first or second set of tanks, the flammable components (such as methane and carbon monoxide) are ignited by electromagnetic igniter one or electromagnetic igniter two before being discharged through exhaust pipe one or exhaust pipe two, respectively, to eliminate safety hazards. The gas discharge rhythm is controlled by exhaust valve one and exhaust valve two to ensure compliant gas discharge. The treated waste liquid is discharged at a controlled pace through drain valve one and drain valve two, and is discharged or recycled through drain pipe one and drain pipe two, meeting environmental protection requirements.

[0041] This technical solution can be connected to another technical solution submitted by our company on the same day, "A mobile biomass material continuous pyrolysis carbonization mechanical equipment". This technical solution also has a modular design, which is convenient for vehicle transportation and movement.

[0042] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
